I think there are 2 sorts of quick flippers and I think they're in a co-dependant relationship:
1. Some people are a little insecure/unsure of their own style and literally need to have what everybody else is talking about (called the 'it', 'must-have' or 'hot' bag etc). Then when the media/market moves on they feel compelled to do so too. This is much quicker than 'looking dated'.
2. People have the consumer clout, time and contacts to buy bags most people can't so use it to literally flip bags and make money like a business. Often these people sell to ^ No 1. flippers.
